The last I read was Varly has "a nagging injury that raises doubts about his availability for Opening Night," according to Barry Trotz.
This is why owning both NYI Gs is mandatory. You can practically hand them the Jennings every year. If your roster allows you to have both guys its really worth doing.
Bummer for Varly if this lingers. But Sorokin is destined to take over at some point.
